In addition to classical radiology systems like angiography, CT scanner or MRI have greatly contributed to the improvement of the patient anatomy investigation. Each examination modality still carries its own information and the need to make a synthesis between them is obvious but still makes different problems hard to solve. There is no unique imaging facility which can bring out the whole set of known anatomical structures, brought together in a neuro-anatomical atlas.

Our perception of the body as the natural “space of the origin and distribution of disease”, a space determined by the 'anatomical atlas', is merely one of the various ways in which medicine has formed its “knowledge”.

Finally, Subsol et al. [6] reported on a method for automatically constructing 3D morphometric anatomical atlantes which is based on the extraction of line and point features and their subsequent non-rigid registration.
